student = [{'id': 1, 'success': True, 'name': 'Lary'},
 {'id': 2, 'success': False, 'name': 'Rabi'},
 {'id': 3, 'success': True, 'name': 'Alex'}]

# Print the sum of 'id' values for all students in the 'student' list.
print(sum(d['id'] for d in student))

# Print the sum of 'success' values (True/False) for all students in the 'student' list.
print(sum(d['success'] for d in student))
